Re: Applications for Consent to the Transfer of Control of Licenses and Authorizations from to WT Docket Number 05-63

Dear Ms. Dortch:

Clearwire Corporation (“”) is filing this letter in support of Nextel Communications’ (“Nextel”) proposed merger with Sprint Corporation (“Sprint”) (the merged entity referred to herein as “Sprint Nextel”).

Clearwire was founded by Craig McCaw in 2003 to provide competitive broadband services to residential and small business customers throughout the United States and around the world. Clearwire has acquired access to 2.5 GHz spectrum in many markets throughout the United States and is operating high-speed wireless nomadic Internet access services for residential customers in several states. Clearwire has embarked on an aggressive roll out schedule and has plans to launch broadband systems in a number of additional markets in the coming months.

In addition, Clearwire is using licensed spectrum to provide wireless broadband services in several international markets including Mexico, Belgium and Ireland. Furthermore, through its wholly owned subsidiary, NextNet Wireless, Inc., Clearwire is developing, manufacturing and selling equipment that enables the deployment of broadband fixed wireless networks in over 30 countries around the world. Thus, Clearwire and its affiliates are clearly among the wireless industry leaders not only throughout the United States but across the globe.

Sprint, Nextel and Clearwire are among the largest holders of spectrum in the Broadband Radio Service (“BRS”) and Educational Broadband Radio Service (“EBS”) 2.5 GHz spectrum band through either license or lease. All three companies have been working cooperatively through the industry association to rationalize the spectrum for wireless broadband service. Given Clearwire’s aggressive “pre-transition” 2.5 GHz deployment, we face a challenging spectrum environment in many markets. We have been encouraged by the willingness of Nextel and Sprint to help assist Clearwire’s service in some of these markets by taking steps to mitigate interference. Nextel’s and Sprint’s cooperation demonstrates their commitment to competition in the broadband wireless market. We expect that this cooperative behavior will continue as the industry works to maximize the efficiency of BRS/EBS spectrum band that has been underutilized for many years and facilitate competition.

Both Nextel and Sprint have been exemplary members of the wireless business community and Clearwire believes that they will continue that tradition as the merged company continues to intensely compete in multiple sectors of the communications industry. As an independent operator, Sprint Nextel also can help attract investment to development of wireless services at a time when consolidation in the market by horizontally integrated wired and wireless operators could inhibit innovation in the broadband wireless sectors.

Clearwire thus supports the proposed merger between Nextel and Sprint. Pursuant to Section 1.1206(b)(2) of the Commission’s Rules, this presentation is being filed electronically. Should any questions arise concerning this matter, kindly contact the undersigned.

Sincerely,

/s/ R. Gerard Salemme
